Product Overview

DC1649A-A demonstration board features the LTC6945, an ultralow noise and spurious integer-N synthesizer. Its is a high performance, low noise, 6GHz phaselocked loop (PLL), including a reference divider, phase frequency detector (PFD) with phase lock indicator, charge pump, integer feedback divider and VCO output divider. The LTC6945 is designed to work in conjunction with an external low noise VCO up to 6GHz. In addition, the device has an on chip output divider that is programmable from 1 through 6 to extend the tuning frequency coverage to as low as 350MHz. The on chip SPI compatible bidirectional serial port allows frequency tuning and control, and read back of the register and loop status information. The DC590 board and PLLWizard application are required to control the DC1649A. The PLLWizard comprehensive PC based design tool software is used to communicate with the LTC6945 synthesizer and uses the DC590 to translate between USB and SPI compatible serial communications formats.
  • Low noise integer-N PLL
  • Excellent spurious performance
  • Output divider (1 to 6, 50% Duty cycle)
  • Low noise reference buffer
  • Output buffer muting
  • Configurable status output
  • SPI compatible serial port control
